We conduct a field experiment in a naturally occurring labor environment and track whether the performance of workers responds to unexpected wage increases. Specifically, we investigate how the timing of wage increases affects efforts. We find that workers' performance is about 11% higher for...

By conducting a natural field experiment, we test whether a managerial policy of allowing employees to self-determine their wages is as successful as recently suggested by laboratory evidence. We find that this policy indeed enhances performance. However, our data is clearly at odds with the...

We investigate the difference between monetary incentives and monetary gifts on employees’ performance using a firm-level field experiment. We randomly assign store managers of a German discount supermarket chain to two different groups. In the first treatment, the store managers receive a...

Recent laboratory evidence suggests that employees who have the extraordinary right to self-determine their wages perform better. By conducting a natural field experiment, we aim to test whether this policy actually has the predicted positive effects in a real-labor market. Employees were hired...

There is now an extensive literature on "gift exchange" showing that when principals and agents can trade "gifts" (rewards that should not emerge in a competitive equilibrium), exchange becomes more efficient. However, it is not obvious how gift exchange should be organized if the principal's...

We ran a field experiment in a Dutch retail chain consisting of 128 stores. In a random sample of these stores, we introduced short-term sales competitions among subsets of stores. We find that sales competitions have a large effect on sales growth, but only in stores where the store's manager...

We conduct a field experiment among 189 stores of a retail chain to study dynamic incentive effects of relative performance pay. Employees in the randomly selected treatment stores could win a bonus by outperforming three comparable stores from the control group over the course of four weeks....
